Core web vitals are important factots to qualify how good is your web page.
User experience has always been an essential part of building the best site out there, but now, it will play an even bigger role in helping you build awesome sites for your customers. All this is powered by new metrics, with at the center: the Core Web Vitals. Time to meet LCP, FID, and CLS!
If you’re already familiar with these terms, feel free to skip ahead to the “What’s New” section. But if you’re not sure what we’re talking about, don’t worry—we’ll explain everything!
The three new metrics that we’ll be using are called LCP (Loading Component Pause), FID (First Input Delay), and CLS (Critical Layout Speed). These are all related to how fast a page loads and how much time users need to wait before they can interact with it—and they’re going to be the new ranking factor for 2021!

If you’re a developer, it’s important to know what your FID score is. If it’s bad, it means that your site loads in more than 300 milliseconds. You should consider reducing and optimizing your JavaScript execution time.
This means that the time between when your browser executes JS code and when the browser renders the page is reduced.
It’s also essential to use as little memory as possible. Why? Whenever your site’s code requests the browser, it reserves a new memory that stops the JavaScript and might slow down the page.
According to Google, one of the ways you can reduce JavaScript execution time is by deferring unused JS.
Lazy loading is a technique that allows you to load images on your site only when the user scrolls down. This means that you can avoid slowing down the loading speed of your website and keep it at a top-notch level.
In addition to that, lazy loading can improve the performance of your site, reduce bandwidth usage, improve SEO and keep visitors on the page for longer time periods.
You probably know that images are one of the most important elements on your website. But did you know that they can also be one of the heaviest?
That’s right: if your site uses lots of images, it can seriously impact how fast your pages load. And that’s not good for anyone—not users, not search engine bots, and not you.
But there are ways to optimize your site’s images to make sure they’re small enough to load quickly but big enough to look great. You can do this by compressing them with a tool like TinyJPG or optimizing them with a software program like Adobe Photoshop (or Gimp).
When you are optimizing your website, you have to make sure that the content is accessible to all users. That’s why it’s important to optimize your website for mobile devices as well. Using the lazy load technique can help you achieve this goal.
Lazy loading refers to loading images only when they are visible in the viewport or when user scrolls down the page. This technique helps you avoid unnecessary bandwidth and improve loading speed by reducing initial overhead of downloading all images on your website.
As we know that not all people use the same internet connection at home or office, it can be a problem for some users who have slower connection speed or slow internet connection. The lazy loading technique helps us solve this problem because we save bandwidth by not downloading all images at once but only when they enter into our screen’s viewport.
You’ve probably heard the phrase “the faster, the better.” But did you know that in terms of your site’s performance, it applies even more to your website’s loading time?
Google says: “The longer it takes a browser to receive content from the server, the longer it takes to render anything on the screen. A faster server response time directly improves every single page-load metric, including LCP.”
Most importantly, long server response time can negatively influence not only your SEO but also UX.
In order to measure server response time, use Time to First Byte (TTFB) that identifies the time the user’s web browser receives the first byte of your page’s content. However, before you start, collect the data on your server’s current performance to understand how you’re doing. When you have done the report, here are tips that will help you:
Review your plugins. Why? It’s because each plugin comes with an additional weight for
